Fan control in $88? (90-92 V6 '730)

Anyone know the location of the fan control for the $88 code? 90-92 LH0 V6 '730 ecm here, thanks

I can't find it in the 730_ATTA.ecu file, so I suppose I'll add it

I've the following data:

(in Hex numbers)

3D6 = C5 = Fan 1 On - AC Off.
3D7 = C0 = Fan 1 Off - AC Off
3D8 = C3 = Fan 1 On - AC On
3D9 = BD = Fan 1 Off - AC On
